Why is it 40 m?

Madhusudan said: (Apr 7, 2016)  
It is not 40 m i.e. 45 m. When the length is more than 45 m we provide an expansion joint for safety.

According to IS 3414: 1968.
Cl no. 6.3.1.

In brick or stone masonry expansion joints normally need not be necessary, except in the case of long walls exceeding 30 m in length; in such long walls the expansion joints shall be not less than 15 mm wide and shall be spaced not more than 30 m apart.

Not in 40m, it is provided just 25 to 30 m length when the length of masnory work is more than 100m.

In brick masonry or stone masonry, it is provided at the expansion joint of 25M to 30M. It is the correct expansion space at a longer wall.
